Because of the movable plunger on a syringe the gas inside, Ask an Expert

Academics

Because of the movable plunger on a syringe, the gas inside the syringe can be held at a constant pressure of 1.00 atm while allowing the volume of the gas to increase or decrease. There are 2.045 x 10 -4 mol of air. Assume mole fraction of nitrogen in air is .79 and the mol fraction of oxygen os 0.21.

A) You trap a small amount of of water inside the syringe (assume water vapor reaches equilibrium, inside syringe, and neglect the volume of the liquid water which will be present) Given a temperature of 25 C, a volume of 5.0 ml and a total pressure of 1.00 atm, determine the partial pressure of water vapor, partial pressure of air (w/o water vapor) inside the syringe, and determine the number of moles of air contained in the syringe.

B) you increase the temp to 65C, the total pressure remains 1 atm, but volume increases. Determine the volume of the syringe at the new temp (Assume water vapor reaches equilibrium at 65 C)
